I am in my 2nd year of teaching (primary), not really happy in my current school and looking to change in September. I am wondering about doing a year of supply just to get a bit more perspective on different schools - I did SCITT training in the school I had worked at as a TA for over 5 years, with one other 6 week placement in a different school, then started in my current school as an NQT. I am pretty sure where I am now is not where I want to be long term - ridiculous amount of paperwork and data analysis, refusal to allow us to use any scheme of work, entire curriculum has to be done from scratch and bespoke to the school, full written planning uploaded every week, all middle leaders (ie everyone apart from me) snowed under trying to produce copious documentation with no TLR or time out of class to do it in. But obviously I don't have much point of comparison to tell whether I would any happier in a different school. So I am wondering whether a period of supply would help me figure out what I actually do want to do. We could comfortably afford for me to earn less then I do now.
I am potentially interested in moving into SEN and also wondering whether secondaries are desperate enough for MFL staff that I might get some supply experience there? (previously taught one MFL at uni level and know a 2nd one well enough to teach KS3 and probably GCSE, also have TEFL experience). Would welcome any ideas/suggestions/advice/wisdom from anyone!
